Abstract
Embodiments of the invention provide Raman spectroscopy methods and devices that exploit high quality factor (Q) resonators to enhance Raman signal by several orders of magnitude over the signal typically expected for Raman methods. Embodiments typically include one or more resonators, typically microtoroid microresonators. Embodiments also take advantage of Rayleigh scattering using these microresonators. Embodiments may be particularly useful for non-labeled nanoparticle sensing.
